There is rotational, have HRB bearing ( ) Jiaxing bearing | bearing excessive vibration cause analysis in the operation of the centrifugal fan. Jiaxing bearing group sales co. , LTD. ( The company) Is jiaxing bearing factory set up in the spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong cash supply ability. Centrifugal fan is a kind of high pressure mechanical energy can be converted to wind power machinery, it is the use of high-speed rotation of the impeller speed, the gas and then slow down, change flow direction, the mechanical energy can transform the wind. We all know that the centrifugal fan consists of chassis, main shaft, impeller, transmission mechanism and the bearings and motor. Centrifugal fan with long hours of work and the bearing will wear it lightly fails, then the following for you to resolve the cause of the centrifugal fan bearing vibration levels. Centrifugal fan bearing vibration is common faults in the operation, the vibration of the centrifugal fan can cause damage of bearing and blade, loose bolts, chassis and air duct damage failure, seriously endanger the safe running of the centrifugal fan. Centrifugal fan bearing vibration to exceed bid more, the cause of such as can according to different phenomenon analysis reason take appropriate treatment method, often can have twice the result with half the effort. Keep furnace processing blade non-working area of gray centrifugal fan vibration caused this kind of defects found in boiler centrifugal fan, phenomenon mainly for vibration in the operation of the centrifugal fan in a sudden rise. , this is because when the gas into the impeller and the rotating blade working face has certain Angle, according to the principle of fluid mechanics, gas from non working face must be a spiral blade, so the dust particles in the gas due to vortex action will slowly in the non-working surface sedimentation. The wing type blades are deposited the most easily. Because of the impeller when the weight of the dust reaches a certain part of the effect of rotating centrifugal force will be large impeller the dust. Because each blade on the dust can't completely uniform, gathered the grey block of time or can be thrown away may not synchronized, the result for blade coating uneven impeller unbalanced mass distribution, so that the centrifugal fan vibration increase. In this case, just put on the blade usually dust remove, impeller and to achieve balance, thus reducing the vibration of the centrifugal fan. In actual work, the general treatment method is a temporary halt to the furnace after open centrifugal fan casing manhole door, maintenance staff into clear the dust on the impeller casing. Bad environment not only so, unsafe factors are and unscheduled shutdown of the unit, maintenance time is long, the intensity of labor is big. Through the research, proposed a proved by actual effective treatment method. By adding a row in the chassis mouthpiece nozzle ( 4 ~ 5) Turn, nozzle into different angles. Nozzle with ash pump is linked together, will be deposited as flushing ash water dynamic medium, reduce the load after unilateral centrifugal fan, at the instant of the centrifugal fan stop quickly open the valve, using the inertia effect of the impeller spray cleaning blade on the working face, open the chassis mounted at the bottom of the ash water valve is going. Thus to realize the furnace and deal with the purpose of the centrifugal fan vibration. Made clear ash ash water medium, and compared with steam and compressed air, has low requirements for nozzle structure, large range of ash removal, and the advantages of small effect is good, the blade wear. To sum up, the harm of centrifugal fan bearing vibration are high, so we when in use at ordinary times should pay attention to check whether there is a heavy on centrifugal fan impeller, if any, should be immediately clear, avoid causing excessive bearing vibration, and damage the centrifugal fan. 24-hour customer service hotline: if you are more interested in jiaxing bearing the author introduced the industry information or have any questions, please click on contact us page on the right side of the online customer service, or call:, you close the way of jiaxing bearing purchasing advisors. - - - - - - Editor: jiaxing bearing sourcing consultant LTD.
